How have ideas about the atom changed in the last two centureies?
dsp73
In the past a scientist named dalton produced an atomic theory. There were certain problems regarding his views. So, later on scientists like chadwick, rutherford and thompson added some fresh light for the real identification of the atom.
dalton said the atom was the smallest unit and it CANNOT BE DIVIDED ANY FURTHER.
NOTE... this was renected with the discovery of the proton, neutron and electron as the sub atomic particles.

What is the mass of a 1.71-l sample of a liquid that has a density of 0.921g/ml?
Temka [501]
Hey there!:

Volume in mL :

1.71 L * 1000 => 1710 mL

Density = 0.921 g/mL

Therefore:


Mass = Density * Volume

Mass = 0.921 * 1710

Mass = 1574.91 g

A fixed amount of gas in a rigid container is heated from 300 k to 900 k, which of the following responses best describes what w
Llana [10]

Answer: Option d. pressure increase by a factor of 3

Explanation:

P1 = P

T1 = 300k

T2 = 900K

P2 =?

Volume is constant.

P1/T1 = P2/T2

P/300 = P2/900

P2 x 300 = P x 900

P2 = (P x 900)/300

P2 = 3P

The pressure increased by a factor of 3

if multicellular organism came from unicellular organisms, then are all species ralated, why do you think so?​
Alenkinab [10]

Answer:

Explanation:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.
